Abstract
PURPOSE:To prevent the boiling given by overshooting for raising the supplying temperature of hot water sufficiently by changing the set temperature of hot water according to the raising speed of hot water in a boiler. CONSTITUTION:A bridge is formed by a temperature detecting thermistor 1, resistances 2 and 3, and a set temperature changeable circuit 4, and a fuel control circuit 5 is operated by the output of a transistor 6. The resistance between the base and the negative terminal of a transistor 6 is raised in a stepped state by the circuit 4 as Th1 in the graph shows, and when the hot water temperature W1 is increased over the set temperature Th1 at a temperature TA, combustion is intermitted by the operation of the circuit 5 and the raising of the set temperature by the circuit 4 is also stopped. When the hot water temperature W1 is decreased, the combustion and the raising of the set temperature are restarted by circuits 4 and 5 for making a steady combustion at a temperature TB. Since the rising speed is slow in the supplying temperature W2 of hot water, the set temperature is also raised in a slow speed.
